This listing is for an autographed Shaquille O'Neal jersey. The jersey has been authenticated by PSA/DNA (one of the best authentication companies).
It has the tamper proof sticker/hologram and certificate of authenticity COA card. This jersey would be a great addition to any collection! I have a bunch of other autographed jerseys, helmets, and baseballs authenticated by TRISTAR, JSA, PSA/DNA, STEINER, SCHWARTZ, and LEAF.
